A teaser for Season 2 of "Vikings" caused a stir when History Channel screened it at San Diego Comic-Con in July, and it still has fans riled up.

The teaser shows the army of the series' main character, Ragnar Lothbrok (Travis Fimmel), battling the forces of his brother, Rollo (Clive Standen). Fans will remember that as Season 1 ended, Rollo decided to turn against Ragnar in a bid for glory of his own. He sided with Jarl Borg, the leader of another group of vikings.

The clip could be a deception and Floki is just badly injured. But Skarsgärd wasn't going to tell reporters how long he'd be around in Season 2, which the cast is filming now. The new season will begin in early 2014 on History.

"I'm in the first episode, I guarantee that," he said, adding that all the actors read their scripts with a bit of trepidation.

"It's like unwrapping gifts at Christmas, but there could also be a bomb in there," he said. "Whenever you read a script you're like, 'OK am I gonna die in this episode? What's going to happen?'

"It's scary to not know where a character's going to go."

Let's hope Floki recovers from Rollo's beat-down, and isn't whisked from the battlefield to sit with Odin in Valhalla.

History Channel's hit drama "Vikings" began with Ragnar Lothbrok and his brother, Rollo, defeating dozens of warriors in a bloody battle. But as the series ends its freshman season Sunday, the brothers probably won't be standing together.
